Abstract

In one embodiment, a method for manufacturing an artificial eyelash includes configuring a placement mark on a surface, positioning a plurality of fibers on the surface based on the placement mark, placing a first adhesive near a base of the plurality of fibers to secure the plurality of fibers together, placing a second adhesive near the base of the plurality of fibers, and cutting the plurality of fibers in accordance to a predetermined shape. In particular, the second adhesive is a pressure-sensitive adhesive.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for manufacturing an artificial eyelash kit, the method comprising:
 configuring a placement mark on a surface;   positioning a plurality of fibers on the surface based on the placement mark;   placing a first adhesive near a base of the plurality of fibers to secure the plurality of fibers together;   placing a second adhesive near the base of the plurality of fibers, the second adhesive being a pressure-sensitive adhesive;   cutting the plurality of fibers in accordance to a predetermined shape to form one or more artificial eyelash segments; and   providing a third adhesive configured to be applied to a user's natural eyelashes;   wherein, for each of the artificial eyelash segments, the artificial eyelash segment is configured to be secured to at least a portion of the user's natural eyelashes at a location corresponding to the second adhesive and where the third adhesive is applied to the user's natural eyelashes, and   wherein an application of the second adhesive with the third adhesive creates a bond that attaches the artificial eyelash segment to the user's natural eyelashes and allows relative movement between the user's natural eyelashes and the artificial eyelash segment at the location.   
     
     
         2 . The method of  claim 1 , wherein the first adhesive is placed under the plurality of fibers. 
     
     
         3 . The method of  claim 1 , wherein the second adhesive is placed over the plurality of fibers. 
     
     
         4 . The method of  claim 1 , wherein the first adhesive is configured to cure prior to cutting the plurality of fibers. 
     
     
         5 . The method of  claim 1 , further comprising:
 applying pressure to the second adhesive to adhere the second adhesive to the plurality of fibers or the first adhesive.   
     
     
         6 . The method of  claim 5 , wherein the applied pressure is in a range from 95 N/cm 2  to 100 N/cm 2 . 
     
     
         7 . The method of  claim 1 , further comprising:
 pressing the second adhesive against the plurality of fibers or the first adhesive.   
     
     
         8 . The method of  claim 7 , wherein the second adhesive is pressed against the plurality of fibers or the first adhesive for at least three seconds. 
     
     
         9 . The method of  claim 1 , wherein a side of the second adhesive facing away from the plurality of fibers is covered by a protective layer. 
     
     
         10 . The method of  claim 1 , further comprising:
 arranging the plurality of fibers at a particular density.   
     
     
         11 . The method of  claim 1 , further comprising:
 curling the plurality of fibers.   
     
     
         12 . The method of  claim 1 , wherein the second adhesive is different from the third adhesive. 
     
     
         13 . The method of  claim 1 , wherein the first adhesive is placed on top of the plurality of fibers. 
     
     
         14 . The method of  claim 1 , wherein the placement mark is an indication for alignment of the plurality of fibers. 
     
     
         15 . The method of  claim 1 , wherein the placement mark is a guide for alignment of the plurality of fibers. 
     
     
         16 . A system for manufacturing an artificial eyelash kit, the system comprising:
 means for configuring a placement mark on a surface, wherein the placement mark indicates locations to place a plurality of fibers on the surface;   a first adhesive configured to be applied near a base of the plurality of fibers to secure the plurality of fibers together;   a second adhesive configured to be applied near the base of the plurality of fibers, the second adhesive being a pressure-sensitive adhesive;   means for cutting the plurality of fibers in accordance to a predetermined shape to form one or more artificial eyelash segments; and   a third adhesive configured to be applied to a user's natural eyelashes;   wherein, for each of the artificial eyelash segments, the artificial eyelash segment is configured to be secured to at least a portion of the user's natural eyelashes at a location corresponding to the second adhesive and where the third adhesive is applied to the user's natural eyelashes, and   wherein an application of the second adhesive with the third adhesive creates a bond that attaches the artificial eyelash segment to the user's natural eyelashes and allows relative movement between the user's natural eyelashes and the artificial eyelash segment at the location.   
     
     
         17 . The system of  claim 16 , wherein the first adhesive is placed under the plurality of fibers. 
     
     
         18 . The system of  claim 16 , wherein the second adhesive is placed over the plurality of fibers. 
     
     
         19 . The system of  claim 16 , wherein the first adhesive is configured to cure prior to cutting the plurality of fibers. 
     
     
         20 . The system of  claim 16 , wherein the second adhesive is configured to be adhered to the plurality of fibers or the first adhesive with application of pressure. 
     
     
         21 . The system of  claim 20 , wherein the applied pressure is in a range from 95 N/cm 2  to 100 N/cm 2 . 
     
     
         22 . The system of  claim 16 , wherein the second adhesive is pressed against the plurality of fibers or the first adhesive. 
     
     
         23 . The system of  claim 22 , wherein the second adhesive is pressed against the plurality of fibers or the first adhesive for at least three seconds. 
     
     
         24 . The system of  claim 16 , wherein a side of the second adhesive facing away from the plurality of fibers is covered by a protective layer. 
     
     
         25 . The system of  claim 16 , wherein the plurality of fibers are arranged at a particular density. 
     
     
         26 . The system of  claim 16 , wherein the plurality of fibers are curled. 
     
     
         27 . The system of  claim 16 , wherein the second adhesive is different from the third adhesive.
